Ken, I can send you my old parts and you can experiment to

your hearts content. The rotor I am

 discarding is original 1977 Harley and is not suited to

adaptation, the spline for the crank was a

 machined part spot welded to the rotor face, the new part

has the spline cut into the rotor face

 and uses separate spacer washers. The 22 amp upgrade kit

(H-D p/n 29982-81) should work real well.

 I'm considering the same thing. The kit price varies by

dealer, I was quoted as high as $225, but

 found another dealer who would sell it for $182 and honor a

15% discount coupon I had. The kit

 includes rotor, stator, and rectifier.

Rick,
My thought was to machine out the splines to a 'slipper' fit around Tracy's input shaft.  This would keep the flywheel/rotor
centered and also relieve the stress on the rivets or bolts holding the flywheel/rotor to Tracy's flywheel.  Thanks for the
offer of borrowing your old parts but I don't think that is neccessary.  How 'thick' is the Harley flywheel (not diameter)?
What we need to calculate is how much longer Tracy's input shaft, redrive spacers and bolts would need to be?
Thanks for the info.

Ken, the Harley's flywheels are inside the engine case on either side of the crank pin. The splines are cut into the output
shaft and the alternator resides inside the primary drive case on the left side of the engine.
